INKING DEVICE.

To all whom it may concern:

Be it known that l, `WALTER @rumena FIELD, a subject of Great Britain, residing at Romford, F-ssex, England, have invented new and useful Improvements in lnking Devices, of which the following is a specification.

The invention relates to inking devices in which rollers are required to deliver ink to a pad or the like passing around them, and is specially applicable to duplicators in which two or more rollers are used around which the stencil and its pad travel.

The object of the invention is to construct a self-feeding inking roller which can be operated at intervals to deliver a limited quantity of ink to the pad.

The invention consists in forming the roller with an ink reservoir and providing means for discharging a definite quantity of ink from such a reservoir when required by a single operation.

The invention further consists in an inking roller having a circumferential reservoir and an internal rotating part adapted to cause the discharge of ink from the reservoir when rotated relatively to the inking roller.

rllhe invention also consists in means comprising a lever and cam surface actuating a ratchetwhcel for causing the rotation of the internal rotating part relatively to the roller.

The invention also consists in causing the ink delivery devices to free a catch and allow the lever and cain surface to be automatically put out of operation when the ink delivering devices have been actuated.

The invention further consists in a duplicator in which the stencil and its pad pass around two or more rollers one of which is a self feeding inking roller which is caused to deliver a given quantity of ink to the pad by the single operation of a lever or the like.

The invention also consists in the iniproved inking devices for duplicators or the like hereinafter described.

YV ith reference to the accompanying drawings. Figure l is a longitudinal section of the inking roller. Fig. E). shows a cross section on the line rfi Fig. l. Fig. 3 is an end view of the ratchet gear. Fig. t shows Specification of Letters Patent.

the cross section of the ink receiver on the line B B Fig. 1. Fig. 5 shows an external view of the roller with its connections to the machine. Fig. 6 shows an end view of the same. Fig. 7 is a section, showing devices by which air can escape from the roller, on the line C C Fig. l, while Fig. 8 is a section taken on the line D D Fig. 7.

In carrying the invention into eect according to one form as applied to a duplicator in which the stencil. and pad pass around the ink roller; the inking roller is formed of an outer tube, a, having perforations, b, for the delivery of ink. The tube is fast on two end disks, c, d, of which c, is fast on the shaft, t, by which the roller is rotated. A piece of sheet metal, e, extending the who-le length of the roller is fixed at its longitudinal edges to the inside of the tube forming therewith a delivery reservoir, f, from which the ink passes through the perforations, Z), to the outside of the roller. A second shaft, g, coaxial with the driving shaft enters the roller at the end opposite the driving shaft and has keyed to it cylindrical pieces, 7L, of less diameter than the tube and forming with such tube a circumferential reservoir for holding ink; slots are formed in these cylindrical pieces and in these slots are placed plungers, 7c, pressed outward by means of springs so that they bear against the inner surface of the tuloe and when the cylindrical pieces, L, are rotated relatively to the tube, sweep ink from the circumferential reservoir into the delivery reservoir, f, through suitable apertures, 2', provided for this purpose.

An intermediate dividing body, Z, forms a partition between the cylindrical pieces and is provided with a space, m, from which ink passes through suitable apertures, n, to the main circumferential ink reservoirs on each side of it.

In order to charge the roller a passage, 0, is formed inthe dividing body and in this passage a plunger, 79, slides covering in its normal position a passage, q, leading to the ink space, mi, in the dividing body; when ink is required the mouth of the ink container is screwed or otherwise inserted into this passage and presses the plunger' y), back against a spring until it uncovers the passage, g, to the ink space; on removing the container the plunger is pressed outward by the spring' closing the ink outlet.

In order to rotate the cylindrical pieces, k, relatively to the roller a ratchet wheel, fr, is keyed to the shaft, g, carrying them; when the roller is in operation and not delivering ink the ratchet wheel, 1, is carried around by means of a pawl, a, carried by the roller. Then relative motion is required in order to force ink from the circumferential reservoir to the delivery reservoir, f, alever, u, pivoted to the frame of the machine is depressed bringing a cam surface, y, into such a position that during the rotation of the roller it bears against a pin w, on a pawl carrying slide, a, that is attached to end-disk rl by means of two screws fu and elongated holes U2 in the pawl carrying slide, moving with the roller and presses this pin, w, and slide, o, inward against the action of a spring, a, causing the pawl, s, carried by the pawl carrier fu, to rotate the ratchet wheel through the space of one or more teeth thus moving thev cylindrical pieces, t, forward relatively to the roller and causing their plungers, 7s, to force ink into the delivery reservoir, f, from which it passes directly on to the pad. Duringv the continued rotation of the roller, the pin, fw, on the pawl carrier clears the cam surface y, on the lever, u, and allows the spring, z, to pull the pawl carrier back causing the pawl, s, to pass back over the teeth of the ratchet wheel. The pin, w, on the pawl carrier, as it presses over the cam surface, y, on the lever, u, comes against a projection, l, on a catch, 2, pivot-ed to the lever, u, and frees this catch so that the lever u, is drawn back by a spring, 3, carrying its cam surface out of the path of the pin, fw, on the pawl carrier which then rotates without operating the ink delivery devices until the lever is again pressed.

In order to fill the circumferential ink reservoir the internal cylindrical part, h,- is turned until the plungers, 7c, therein are adjacent to the ink delivery reservoir so that they are in their inmost position and in this position there are free passages 4t, through the internal cylinder and plungers to the ink delivery reservoir. There are also provided two passages 20, leading from the circumferential reservoir to the outside of the roller by which air can pass from the said reservoir during filling. Further these passages prevent the formation of a vacuum in the circumferential reservoir when ink is being discharged into the delivery reservoir. On rst filling the ink passes into the delivery reservoir through the passage 2', and fills this reservoir which then always remains full of ink. As the ink rises on the two sides of the circumferential reservoir, the air from one side passes through the passages 4L, and so to the passages 20, and from the other side passes directly from the roller through the passage 20. Then the roller is completely filled, ink discharges from all the perforat-ions, Z), as well as the end passages 20.

The inking roller may be arranged to work in conjunction with two rollers, 5, G, Fig. 6, one at either side and the feeding mechanism so arranged that all the ink discharged is met by the rollers before being transmitted to the stencil and its pad. These rollers may be of the waver type, that is, having a reciprocating movement with regard to their longitudinal axes which assists in the equal distribution of the ink.

To prevent the inking lever, a, from being operated when the waiver rollers are not in position a push spindle, 7, is provided which is connected to two shafts, 8, which slide in the frame of the machine directly under the ends of the bearing pins, 9, that carry the waver rollers. One of these shafts is provided with a slot, l0, and the inking lever, u, can only be operated when this slot is in a given position; cam notches are also formed on the shafts, S, and control the bearing pins, 9, of the waver rollers allowing these to rest on the inking roller when the push spindle, 7, is in its outward position.

To prevent the waver rollers, 6, from resting on the inking roller, u, when the maw chine is not in use the push spindle, 7, is so arranged that it must be pushed home before the cover can be put on, the cam notches being so placed that the waver rollers are then out of contact with the inking roller.

An index finger l2, Fig. 3, may be arranged on the ratchet wheel to indicate the amount of ink in the roller.

The above described inking devices are especially suitable for use with inks of a thick consistency, such as the class of inks known as oil inks.
